IATOR-SHIELD.

To all whom it may concern:

Be it known that I, CLARENCE C. Srnrr,

a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Radiator- Shields, of which the following is a specification.

This invention relates to a shield for inclosing steam radiators employed for heat ing public and private buildings; and one of the objects of the invention is to provide a shield of the above character Which will be neat, attractive, ornamental in appearance and cheap to manufacture.

A further object of the. invention consists in the provision of a shield of the above character which is provided with means for storing water for maintaining the requisite per cent. of humidity within the room, automatic means being provided for replenishing the water in the storing means when the water has been reduced in volume through evaporation to a determined point.

A still further-object of the invention consists in the provision of a shield of the above character which is arranged in halves which by means of the construction illustrated in the accompanying drawings, forming a part hereof, in which Figure 1 is a top or plan view of a conventional style of a radiator showing my invention in operative position. Fig. 2 is a front elevation of the construction shown in Fig. 1. Fig. 3 is an end elevation. Fig. 4 is a vertical section on the line 4-4 in Fig. 2. Fig. 5 is a fragmentary detail horizontal view of a portion of the shield showing the means for holding water, on the line 55 in Fig. 6. Fig. 6'is a view in elevation of the construction shown in Fig. 5. Fig. 7 is a section on the line 77 in Fig. 6. Fig. 8 is Specification of Letters Patent.

a fragmentary detail sectional view showing the clamp for'holding the overlapping ends of the two sections of the shield together. Fig. 9 is a View partly in elevation and partly in section showing the device for admitting water to the water holding means.

Referring to the drawings, 10 represents the several assembled sections forming a conventional style of a steam radiator. The shield for inclosing the radiator comprises a lower section consisting of a front member 11 and a rear member 12, which are usually composed of cast iron and which are held together in operative position by means of the bolts 18 extending horizontally across the ends of said members. The rear member 12, in case the shield is employed in connection with a wall air intake, is provided with an opening which is surrounded with the neck 15 to which an air duct (not shown) may be connected.

The radiator shield proper comprises two members 16 and 17 which are composed of sheet metal, and these members are bent to correspond to'the contour of the base members 11 and 12, the latter being attached to the upper members by means of the screws 18. The ends of members 16 and 17 overlap each other, as shown in Fig. 3, enabling the members to be adjusted toward and away from each other without producing an I Patented Mar. t, 191$.

intervening opening, the adjustability enabling the shield to accommodate radiators of different widths. The members 16 and 17 when adjusted are held in position at the top by means of the tiebolts 20. The overlapped portions of the members 16 and 17, which form the ends of the shield, are held together by means of suitable U-shaped clamps 21. See Figs. 3 and 8. The upper edges of the members 16 and 17 forming the front and back of the shield are rolled into two curls 19 for strengthening said members As stated in the objects of the present invention, certain means is provided for maintaining a suflicient supply of Water within the shield, this water being subjected to heat will evaporate causing the air within the room to be charged with desired amount of moisture; and further, that the amount of water evaporated can be automatically replaced as evaporation proceeds. Water is confined within the shield by securing'to the inner surfaces of the members 16 and 17 the corrugated metal sheets 25 to provide reservoirs or pockets 25*, and leakage is prevented by means of a plurality'of closely placed rivets 26 which extend along both sides and bottom of said sheets. The upper ends of the corrugations are left open to permit'the duced through the action of evaporation, I

provide means for automatically replenishing the supply in order that the desired per cent. of moisture in the room can be maintained. This I accomplish by tapping one of the radiator coils near the end of the radiator farthermost removed from the feed pipe 27 through which steam is supplied and where the greatest condensation exists. To the tapped radiator coil I attach a pipe 30 (Fig. 9) which bifurcates so as to allow a branch pipe 31 to extend to each side of the radiator and discharge behind the sheets 25 attached to the inner Walls of the shield members 16 and 17. The ends of the branch pipes are enlarged as shown and are provided with conically shaped. openings to form seats for the needle valves 32, and the valve stems have a slight vertical movement through webs 33 extending across the ends of the openings in the enlargements on the ends of the branch pipes 31, the vertical movement of the stems being limited by means of the transverse pins 34; contacting said Webs 33. The passageways in the branch pipes 31 are sufficiently small in diameter and hence will so reduce the pressure of steam from within the radiator that the maximum pressure developed will be insufficient to overcome the buoyancy of the hollow bells 35 when floating, so that the valves 32 are kept seated and discharge of water through the pipes 31 is prevented. When however the stage of Water held in re straint by the corrugated sheets 25 has been reduced through evaporation to no longer float the bells 35 the latter will drop by gravity, causing the needle valves to move away, from their valve seats and allow Water to discharge through the pipes 31 behind the corrugated sheets 25 until the Water level has 1,17e,eae

again been raised to again float the bells 35 which causes the needle valves to be seated again, When the further discharge through the pipes 31 is discontinued, the operation of the parts being repeated When the Water level has again been reduced through evaporation.

Having thus fully described my said invention, What I desire to secure by Letters Patent, is

1. A shield for incas'ing steam radiators, comprising two adjustable members, sheets secured to the inner walls of said members to form pockets for storing a determined supply of water, and means actuated by a reduced water level in the pocket for automatically restoring the amount of Water lost by evaporation.

2. A shield for incasing steam radiators, comp-rising two adjustable members, means for holding the overlapped ends of said members in adjusted position, sheets secured to the inner Walls of said members'to form pockets for storing a determined supply of water, and means actuated by a reduced volume of water in the pocket for automatically restoring the amount of Water removed from the pocket through evaporation.

3. A shield for incasing steam radiators, comprising two members, corrugated sheets secured to the inner walls of said members to provide pockets for stdring a determined supply of water, and means actuated by a reduction in volume of the stored Water for restoring the amount of Water evaporated from the pocket.

4:. The combination, with a steam radiator, of a shield comprising a radiator incasing member, means arranged on the inner wall of said member to provide a pocket for storing a, determined supply of water, a water conducto'rnneans connecting said pocket with the interior of the radiator for conducting water to said pocket, and means actuated. by the rise and fall of the Water level in the pocket for starting and stopping the flow of water through said water conductor-means.

In witness whereof. I have hereunto set my hand and seal at Indianapolis, Indiana, this 12th day of November, A. D. one thousand nine hundred and fifteen.
